Hi Antoine,

In the broker traces, I see connection shutdown after the transfer but before you shut down the broker. Do you know what is happening there? What was the disposition of the delivery?

Hello Qpid community,



I’m testing the resilience of a dispatcher/broker infrastructure and I
noticed the following behavior:



I run a test with one JMS client connected to a dispatcher, which is
connected to a broker.



1)      Using JMS I establish a connection to the dispatcher and create a
message producer

2)      I’m able to send a message to the broker through the dispatcher

3)      I stop and restart the broker

4)      I cannot send any messages using the message producer I created
before.

5)      If a recreate a MessageProducer (new AMQP link), the message
arrives to the broker



In the failing scenario 4, I noticed using Wireshark that the dispatcher
does not send any messages to the broker. So I deduced that the broker is
not responsible for this behavior.



*Is it an expected behavior? What can I change in the dispatcher/JMS
configuration to avoid the failure?*



You can find attached the Wireshark logs I produced from this experiment:



-          JMS – dispatcher – reuse sender: logs between JMS and the
dispatcher when I reuse the message producer after the restart

-          JMS – dispatcher – new sender: logs between JMS and the
dispatcher when I create a new message producer after the restart

-          dispatcher – broker – reuse sender: logs between the dispatcher
and the broker, I reuse the message producer

-          dispatcher – broker – reuse sender: logs between the dispatcher
and the broker, I create a new message producer



I’m using qpid-dispatch 0.6.0, JMS 0.9.0 and qpid-java-broker 6.0.1.



Thanks,

Best regards,

Antoine
